Continuity mistake: At the end of the episode, when Lister says, 'I'm saying nothing man, don't want to spoil the surprise,' his hood and locks are arranged completely different than all other shots in the scene.

Visible crew/equipment: In the cargo hold, when Lister says 'He really loved that bird', just before Pete turns into a dinosaur, a crew member can be seen walking around in the background, despite the rest of the crew being frozen in time.

Continuity mistake: At the end of the episode when the third Rimmer appears from inside the sink, the reflection of Lister on his bunk in the mirror shows he has a blanket over him. In the wide shot there is no blanket.
